Comment (by edge22):

 Looked into this more, and have attached a super simple test plugin.

 http://demo.generatepress.com/hosted/test.zip

 I've figured out this issue has to do with the active_callback parameter.

 To see for yourself:

 1. Install and activate the attached test plugin
 2. Go to "Customize" and open the "General Settings" panel.
 3. Now navigate to another page - the panel will disappear because the
 active_callback is set to "is_front_page".
 4. Now navigate back to the front page, and open the panel - all of the
 contents have shifted up.

 Another view, with more shift:

 1. Open the "General Settings" panel.
 2. Go back to all of the settings.
 3. Navigate to another page.
 4. Navigate back to the front page.
 5. Open the "General Settings" panel - all contents have shifted up twice
 as much as the previous method.

 This is happening in all modern browsers, using the TwentyFifteen theme.

 Thanks!
